Aging: What to expect

Wonder what's considered a normal part of the aging process? Here's what to expect as you get older — and what to do about it.
By Mayo Clinic Staff

You know that aging will likely cause you to develop wrinkles and gray hair. But do you know how the aging process will affect your teeth, heart and sexuality? Find out what kind of changes you can expect in your body as you continue aging — and what you can do to promote good health at any age.

Your cardiovascular system

What's happening
As you age, your heart rate becomes slightly slower and your heart might become bigger. Your blood vessels and your arteries also become stiffer, causing your heart to work harder to pump blood through them. This can lead to high blood pressure (hypertension) and other cardiovascular problems.

What you can do
To promote heart health:

Include physical activity in your daily routine. Try walking, swimming or other activities you enjoy. Regular moderate physical activity can help you maintain a healthy weight, lower blood pressure and lessen the extent of arterial stiffening.

Eat a healthy diet. Choose vegetables, fruits, whole grains, high-fiber foods and lean sources of protein, such as fish. Limit foods high in saturated fat and sodium. A healthy diet can help you keep your heart and arteries healthy.

Don't smoke. Smoking contributes to the hardening of your arteries and increases your blood pressure and heart rate. If you smoke or use other tobacco products, ask your doctor to help you quit.

Manage stress. Stress can take a toll on your heart. Take steps to reduce stress — or learn to deal with stress in healthy ways.

Your bones, joints and muscles

What's happening
With age, bones tend to shrink in size and density — which weakens them and makes them more susceptible to fracture. You might even become a bit shorter. Muscles generally lose strength and flexibility, and you might become less coordinated or have trouble balancing.

What you can do
To promote bone, joint and muscle health:

Get adequate amounts of calcium. For adults ages 19 to 50 and men ages 51 to 70, the Institute of Medicine recommends 1,000 milligrams (mg) of calcium a day. The recommendation increases to 1,200 mg a day for women age 51 and older and men age 71 and older. Dietary sources of calcium include diary products, almonds, broccoli, kale, canned salmon with bones, sardines and soy products, such as tofu. If you find it difficult to get enough calcium from your diet, ask your doctor about calcium supplements.

Get adequate amounts of vitamin D. For adults ages 19 to 70, the Institute of Medicine recommends 600 international units (IU) of vitamin D a day. The recommendation increases to 800 IU a day for adults age 71 and older. Although many people get adequate amounts of vitamin D from sunlight, this might not be a good source for everyone. Other sources of vitamin D include oily fish, such as tuna and sardines, egg yolks, fortified milk, and vitamin D supplements.

Include physical activity in your daily routine. Weight-bearing exercises, such as walking, jogging, tennis and climbing stairs, and strength training can help you build strong bones and slow bone loss.

Avoid substance abuse. Avoid smoking and don't drink more than two alcoholic drinks a day.

Your digestive system

What's happening
Constipation is more common in older adults. Many factors can contribute to constipation, including a low-fiber diet, not drinking enough fluids and lack of exercise. Medications — such as diuretics and iron supplements — and certain medical conditions — such as diabetes and irritable bowel syndrome — also might contribute to constipation.

What you can do
To prevent constipation:

Eat a healthy diet. Make sure your diet includes high-fiber foods, such as fruits, vegetables and whole grains. Limit meats that are high in fat, dairy products and sweets, which might cause constipation. Drink plenty of water and other fluids.

Include physical activity in your daily routine. Regular physical activity can help prevent constipation and is important for your overall health.

Don't ignore the urge to have a bowel movement. Holding in a bowel movement for too long can cause constipation.

Your bladder and urinary tract

What's happening
Loss of bladder control (urinary incontinence) is common with aging. Medical conditions, such as diabetes, might contribute to incontinence — as can menopause, for women, and an enlarged prostate, for men.

What you can do
To promote bladder and urinary tract health:

Go to the bathroom regularly. Consider urinating on a regular schedule, such as every hour. Slowly, extend the amount of time between your bathroom trips.

Maintain a healthy weight. If you're overweight, lose excess pounds.

Don't smoke. If you smoke or use other tobacco products, ask your doctor to help you quit.

Do Kegel exercises. Tighten your pelvic floor muscles, hold the contraction for five seconds, and then relax for five seconds. Try it four or five times in a row. Work up to keeping the muscles contracted for 10 seconds at a time, relaxing for 10 seconds between contractions.

Your memory

What's happening
Memory tends to becomes less efficient with age. It might take longer to learn new things or remember familiar words or names.

What you can do
To keep your memory sharp:

Eat a healthy diet. A heart healthy diet might benefit your brain. Focus on fruits, vegetables and whole grains. Choose low-fat protein sources, such as fish, lean meat and skinless poultry. What you drink counts, too. Too much alcohol can lead to confusion and memory loss.
